HANDLE FOR LOOK-KNOBS.

Specification of Letters Patent.

Patented July 15, 1913.

Application filed March 15. 1913. Serial No. 754,525.

To all whom 2'2 may concern:

Be it known that I, HARRY ANDERSON, a citizen of the United States,residing in the city and county of Philadelphia, State of Pennsylvania,have invented a new and useful Handle for Lock-Knobs, of which thefollowing is a specification.

My invention consists of an improvement in a handle for lock knobs,etc., and consists of novel means for removably connecting the same inposition.

It further consists in providing means whereby the handle is adapted forvarious sized lock-knobs, etc.

It further consists of novel features of construction all as will behereinafter fully set forth.

The annexed drawing and the following description set forth in detailone mechanical form embodying the invention, such detail constructionbeing but one of the various mechanical forms in which the principle ofthe invention may be used.

Figure 1 represents a perspective view of a handle for lock knobsembodying my invention. Fig. 2 represents a side elevation showing thedevice in position on a lock knob. Fig. 3 represents a sectional viewthereof.

Similar numerals of reference indicate corresponding parts in thefigures.

Referring to the drawings, 1 designates a handle for lock knobs, etc.,comprising an arm or body 2 having the jaw members 3 projectingtherefrom, and to which arm is connected a grasping handle a. As hereshown I have formed the arm and jaws of a single strip and the said jawsbeing preferably of spring material and removable. The strip is suitablybent to accomplish the desired result and I connect the handle 4adjacent the end of the arm 2 opposite to that from which the jaws 3project. Upon opposite sides of the device I provide engaging means hereshown as hooks 5 connected with the arm 2 and situated in suitablerelation to the jaws 8.

6 designates a member, preferably resilient, and here shown as a coiledspring, said member being adapted to be connected with a hook 5 upon oneside and to be broughtaround and to be connected with the hook on theopposite side, with its intermediate portion bearing against the freeends of the jaws 3, spanning and so closing the space between the saidfree ends of said jaws.

The spring may be caused to be connected with the engaging means orhooksin any suitable or desired manner and as here shown I have provided theloops 7 adjacent the ends of the springs for that purpose.

Any suitable means may be provided for holding the spring in suitablerelation with respect to the free ends of said jaws and for this purposeI have shown a recess 8 in each jaw the walls of which recess areadapted to engage the spring 6 to prevent improper lateral movementthereof and s0 hold the spring as stated.

Any suitable means for connecting the handle 4, with the arm 2, may beemployed. As shown I have provided a bushing 9 suitably connected withthe arm 2, and provided with a threaded opening. 10 designates a screwfor engagement with the threaded opening and which screw passes throughthe handle 1 and has a head engaging with a suitable part of the handlein order to prevent displacement thereof but permitting rotary movement.

The operation of the device will be readily apparent. To connect thedevice with the knob 11 of the lock one end of the spring 6 is removedfrom engagement with its respective hook 5 and the jaw members areforced over the knob or shank 12 thereof after which the spring isbrought around the jaw members 8, bearing against the free ends thereofand the end of the said spring 6 is reengaged by the hook 5 so that thedevice is held firmly in position tightly embracing the knob or shank 12thereof and by grasping the handle 4t and rotating the same the knob isturned in unison therewith while accidental removal or displacementthereof is prevented by reason of the spring 6 closing the space betweenthe free ends of the jaw members since in order to release the deviceand to remove the same it is necessary to release one end of the springfrom the hook after which the device can be removed.

It will be seen that by reason of the use of the spring the device isadapted for use on any size knob or shank and is readily adaptedtherefor as will be evident.

Having thus described my invention what. I claim as new and desire tosecure by Let ters Patent, is

1. In a device of the character stated, jaw members having their freeends spaced apart, and a removable longitudinally expansible andcontra-ctible member bearing against the aw mei'nbers, spanning thespace between the free ends thereof and extending in the same directionas said jaw members and adapted for connection therewlth.

2. In a device of the character stat-ed, jaw members having their freeends spaced apart, a removable longitudinally expansible andcontractible member bearing against the jaw members,spanning the spacebetween the free ends thereof and extending in the same direction assaid jaw members and adapted for connection with said aw members, andmeans for connecting said member there with.

3. In a device of the character stated, spring jaws, and alongitudinally expansible and cont-ractible member bearing against thefree ends of said aw and having one end connected adjacent one jaw, andthe opposite end connected adjacent the other jaw.

a. In a device of the character stated, spring jaws, and alongitudinally expansible and contractible member bearing against thefree ends of said jaw and having one end connected adjacent one jaw, andthe opposite end connectedadjacent the other jaw, and means on said jawsfor engagement with said member for holding the same in position.

5. In a device of the character stated, spring jaws suitably supported,and a longitudinally expansible and contractible member bearing againstthe free ends of said jaws and closing the space therebetween, saidmember having one end connected adjacent one jaw and having the otherremovably connected adjacent the other jaw.

6. In a device of the character stated, an arm, jaws projectingtherefrom, an engaging means for each aw, and a longitudinallyexpansible and contractible member bearing against the free ends of saidjaws and having its ends connected with the respective engaging means.

7. In. a device of the character stated, an arm, jaws projectingtherefrom, a hook on each side of said arm, and a longitudinallyexpansible and contractible spring adapted to bear against the free endsof said jaws and having one end rcmovably connected with a hook on oneside, and the opposite end ren'iovably connected with the hook on theother side. j

S. In a device of the character stated, an arm, jaws projectingtherefrom, a hook on each side of said arm, a longitudinally expansibleand contractible spring adapted to bear against the free ends of saidjaws and having its ends connected with said hooks, and means on saidjaws for engagen'ient with said spring for holding the same in suitablerelation to said jaws.
